found it:

The well was cemented up to 18,900', and perforations were then made over 7 higher intervals between 18,199' - 18,689' where significant gas peaks had been
encountered during drilling. These fine-grained sandstone intervals were then subjected to a fraccing procedure. On 12th March it was announced that the
fraccing had achieved only minor gas recovery at a rate too small to measure.
There are several reasons which can explain the absence of significant gas flow, despite the shows during drilling. The most likely explanation is the lack of
sufficient permeability due to the fine-grained nature of the sandstones. The deleterious effects of using heavy mud weight (15.6 lbs/gal) by necessity could also have played a role in impeding gas flow.
